Class SHA3

java.lang.Object

com.entrust.toolkit.security.crypto.digest.sha3.SHA3

public class SHA3
extends java.lang.Object

This is the implementation of KECCAK-p[1600, 24] where 1600 is the width (b) of the permutation in bits, and 24 is the number or Keccak rounds. The width (b) equals capacity + rate. This implementation supports SHA3-224, SHA3-256, SHA3-384 and SHA3-512 where the 224, 256, 384 and 512 is for the bit length.

Since:

9.0
